Real Close dam
Real Close
Real Close is a private irrigation dam located on Duck Creek in Gallatin, Montana. Completed in 1963, this earth dam stands at a height of 15 feet and has a storage capacity of 83 acre-feet. With a primary purpose of irrigation, Real Close plays a crucial role in water resource management in the region, providing water for agricultural activities in the area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Real Close is regulated and inspected regularly to ensure its safety and functionality. Despite being classified as having a low hazard potential, the dam's condition is currently not rated, highlighting the importance of ongoing monitoring and maintenance efforts to mitigate any potential risks. As an integral part of the local water infrastructure, Real Close serves as a vital resource for supporting agricultural practices and sustaining the ecosystem in the surrounding area.
Situated in Congressional District 00, Montana, Real Close is a key component of the water management system in the region, contributing to the overall water supply and irrigation needs of the community. With its location in the picturesque city of Grayling, this dam stands as a testament to the importance of sustainable water resource management and the critical role that infrastructure plays in adapting to the challenges posed by changing climate conditions.

About Real Close
Where does the data for Real Close come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.
